OPHTHALMIC MOUNTING.

Application filed October 20, 1921.

The present invention relates to ophthaL mic mountings and moreparticularly to the type provided with temples and formed wholly ormostly part of cellulose material, an object of this invention being toprovide a strong and durable connection between the temples and the lensframes. A further object of the invention is to provide in a mountingwith non-metallic frames, metallic hinges for the temples, which will beinconspicuous, strong and durable. A still further object of theinvention is to do away in a non-metallic lens'frame with what iscommercially known as the drop temple, that is, one that is so loosethat it folds inwardly by gravity. Another and still further object ofthe invention is to enable the temple pivots to be arranged more closelyto the lenses in that type of mounting made mostly of non-metallicmaterial. Another object of the invention is to provide a metal insertacting as a pivot piece for a temple and so covered as to be invisiblefrom the front or either side of the mounting. A still further object ofthe invention is to provide a construction in which a metallic pivotinsert may be attached to the rear face of the lens frame and maythereafter be covered to provide a pocket about the same which willrender the insert invisible from the front or either side of themounting.

To these and other ends, the invention consists of certain parts andcombinations of parts, all of which will be hereinafter described, thenovel features being pointed out in the appended claims.

Fig. 14 shows the blank folded ready for attachment to a lens frame.

Referring more particularly to the draw ings, 1 indicates the lensframes connected by a bridge 2. The lens frames and bridge are, in thisinstance, both made of non-mepocket forming tallic material such as acellulose compound like pyroxylin, celluloid, etc. The temples 3 are, inthis instance, formed of similar material and are pivotally connectedwith the lens frames.

With the end in view of providing between each temple and its lens framea pivotal connection which will be invisible from the front and sides ofthe mounting and will, at the same time, be of strong and durableconstruction, there may be provided on each lens frame a projection orextension 4 which extends outwardly and rearwardly, each projectionhaving a pocket recess or socket which opens inwardly and rearwardly andis closed at the side, the top and the bottom of the mounting. The sidewalls of this pocket are parallel and the parallel side walls areconnected by a transversely ex- 1tlencling wall and the bottom of thepocket is In the embodiment shown in Figs. 1 to 8, each of these ocketsis provided by a pocket forming mem er 5, formed of non-metallicmaterial and separately from the main portion of the extension 4 andcemented to the rear face of such main portion of the extenon the upper'sion. Within this pocket is the pivoting piece or metal insert or hingemember which comprises preferably an upper leaf portion 6 engagin andtightly fitting the upper side wall oi tie pocket, a lower ,leat portion7 abutting and tightly fitting the lower side wall of the pocket and aconnecting portion 8 abutting and tightly fitting the outer ortransverse wall of the pocket. With the end in View of securing theinsert within the pocket, the former has prongs or ofi-set wings 12 withshoulders 13 anchored or embedded in the trontor bottom wall of thepocket, one of said prongs beingsprovided wall and the-other prong beingprovided. on the lower wall. Tn this embodiment before the pocketforming member is applied, the main portion of the extension Al isformed with two circular openings 14%, the diameter oi these openingsbeing less than the greatest cross dimension otone oi the prongs 12. Thetwo prongs l- Qare heated and are thenforced into the openings 14, thematerial flowing about the anchoring prongs or projections and in backof the shoulders 13, the insertion being continued until the inner wallsof the portions 6, 7 and 8 abut the rear face of the extension 4i. Afterthis abutment takes place, the parts are permitted to cool and theinsert is permanently anchored to the non-metallic part. The poclretforming member 5 is thereafter molded about the insert and at itsforward edge is cemented or otherwise secured to the rear face of themain portion of the extension l.

The upper and lower side walls of each pocket are provided with alinedopenings 9 through which a screw fastener is passed to serve as a pivotfor the temple 3. The

screw fastener is threaded at 10 to engage inthe top portion 6 of theinsert and the upper opening 9 ot the pocket forming memher 5. it.shoulder 10' formed on the fastener is adapted to engage with the lowerside of the pivot piece or terminal 11 ot the temple order draw thelatter firmly against the u. j wall of the insert.

nber or pivot eye 11 may H ng or reinforcing projec ti. with shoulders16 and this heated and forced into an o vess or socket which is madeinto the 2 61 end of the non-metallic portion cat the ice. le, theopening being less in diameter than the greatest cross diameter oi" the15, and the material of the tern-- ple :tlowing leach: ot the shoulders16 and serving to hold the prong after the parts have been cooled. Thepivot piece 11 has shoulder 17 at one side for engagement the connectingportion 8 in order to movement of the temple. end of the non'metahtenants to the exterior of the pocket forming member 5, so-that when thetemple is moved to its outermost position on the lens frame, the pocketforming member forms a substantial continuation ot the temple.

Tn the embodiment of the invention illustra-ted in Figs. 9 to lat thelens frames 1 are each provided with outwardly and rearwardly projectingextensions i at their outer sides and these extensions have pocketsmolded on their inner faces and opening rearwardly and inwar'dly, beingclosed in an upward and" downward direction. Tn these pockets the metalinserts or hinge members are arranged These metal inserts, in thisinstahce, eabh comprise an upper leaf portion' fi and lower leaf portion7 and connecting portion 8", the upper and the lower portion tightlyengaging the upper and the lower'wall of the pocket and the connectingportion tightl" engaging the trans verse wall or" the pocli et. Theinsert is se cured in the pocket through prongs anchored in the forwardwall of the pocket. Tn this instance, the forward wall has threerecesses formed therein, these recesses being, in this instance, cut ordrilled in the forward wall, one in converging relation to the othertwo. The prongs 18 on the portions 6* and 7 are deflected in onedirection and are driven into these last mentioned two openings, thedeflection being shown in Fi s. 9 and 10 and the normal positions outthe prongs being illustrated in Fig. 13. The connecting portion 8 of theinsert has a prong 19 which is deflected toward the prongs 18 when theinsert is driven into the pocket, this deflection being accomplishedthrough engagement of t e prong 19 with the walls of the recess whichthe prong enters in the front wall of the pocket. The temple 3 has aterminal or pivoting piece ll formed with a prong 15 secured to thenon-metallic material of the temple in the same manner as the prong 15in the embodiment shown in Figs. i to 8. A pivot pin 10 with a shoulderl0 and a-screw threaded portion l0 serves to hold the ivot piece ll. inthe insert.

In both il ustrated embodiments of the invention a metal. insert orpivoting piece for the temple terminal is secured in a pocket in therear face of the lens frame, this pocket being closed at its top,-bottomand outer side so that the metallic pivoting piece is invisible in use.The pocket is formed inan outward and rearward extension on the lensframe, and the pivoting piece or, insert is formed with portionsabutting the top, the bottom and the outer side walls of the ocket. Thepivoting piece has its top and bottom portions formed with prongs whichare anchored in'the font wall of the pocket. The temple has a metallicpivoting piece which is anchored in a non-metallic portion andcooperates with the pivoting piece of the lUU ' lens frame to limit theoutward movement .lOl

. of the temple.
